Question

The enol form of acetone, after treatment with $D_{2}O,$ gives rise to:

• A.
• B.
• C.
• D.

Answer 1

The correct option is B


The enol form of acetone on treatment with $D_{2}O$ undergoes enolisation, deutration (addition of $D_{2}O$ ) and dehydration (removal of $H_{2}O$). The repeated enolisation, deutration and dehydration ultimately gives $C{D}_{3}COC{D}_3$.
